I will briefly review the current status of observations of chromospheric flares on the Sun and other cool stars, with a focus on their spectral properties. Modeling the spectra and light curves represents a challenge for our understanding of the underlying physical processes of the energy transport and dissipation. I will discuss different scenarios of the chromospheric-type emission during flares and point to various synergies between solar and stellar cases. I will also show recent SDO/EVE spectra of the Sun-as-a-star, which can provide important links to stellar flare studies.
